[background technique]
In the manufacturing process of display, when closely sealed each other due to components such as plastic cement membrane material, glass substrates in display, The bending or out-of-flatness in structure are generated, will lead to the abnormal absorption of diaphragm in component, this is on the display picture of display One of the main reason for Newton's ring phenomenon occurs.
Before backlight module is bonded with liquid crystal cells, pulling force caused by the protective film of diaphragm above backlight module is removed (off-type force) can take up the glue-line below the diaphragm and diaphragm under protective film, make diaphragm and paste below with the frame of glue frame The glue-line generation of face contact is detached from and arches upward slightly, will cause the partial region of diaphragm and liquid crystal above backlight module after fitting Lower layer's polaroid of unit adsorbs, and causes to have Newton's ring phenomenon on display picture, seriously affects the optics matter of screen The effect that amount is presented with picture.
Fig. 1 is please referred to, the display picture of display pannel 10 has a Newton's ring 90 in intermediate position.
Please refer to Fig. 2, found after technical staff disassembles backlight module and panel, the diaphragm 102 above backlight module with The polaroid 101 of liquid crystal cells lower layer is all around pasted with hollow glue-line 100 at it, the intermediate position of the diaphragm 102 to On arch upward, have adsorption phenomena with the polaroid 101 of liquid crystal cells lower layer, display pannel 10 in the position adsorbed and Fig. 1 Newton's ring 90 to occur position corresponding, based on this discovery, by experimental verification, confirm that above-mentioned adsorption phenomena is to cause newton The reason of ring 90 occurs.
The known means for preventing display picture from Newton's ring phenomenon occur have by maintaining the two when diaphragm is closely sealed each other Between certain gap, to prevent the generation of Newton's ring.Existing motion for example carries out blasting treatment, using in film in membrane surface The one or both sides of piece carry out the thin slice etc. of concave-convex processing, however above-mentioned means by additional processing or need to use additional member, Increase production cost, therefore the present invention propose it is a kind of from source prevent display picture there is the method for Newton's ring phenomenon.
[summary of the invention]
To solve the above problems, the present invention mentions a kind of method for producing panel, Newton's ring phenomenon occurs to solve display picture, Include:
It is roughened on the frame veneer of backlight module glue frame, for promoting the glue frame frame veneer to its top The pull-out capacity of diaphragm above glue-line and glue-line；The off-type force for reducing protective film used in diaphragm above backlight module, for dropping It is low when removing the protective film, to pulling force caused by the glue-line below diaphragm and diaphragm below；And diaphragm with In the glue frame fitting of backlight module, extend the fitting time, it is glutinous for increasing the frame veneer of glue frame of the diaphragm and backlight module With joint efforts.
The roughening treatment uses electrical discharge machining means.
The electrical discharge machining means are carried out with 1 ampere of electric current of tool-electrode.
The electrical discharge machining means by the roughness of the frame veneer of glue frame be machined between 1.0-2.5 microns (μm) it Between.
The means of off-type force for reducing protective film include:
Reduce and removes the angle of protective film, reduces the speed for removing protective film and using the guarantor with lower off-type force At least one of cuticula.
The angle for removing protective film is between 1-5 degree.
The speed for removing protective film is between -30 mm/second of 10 mm/second (mm/s).
The off-type force of the protective film of the lower off-type force of tool is between 50-100 grams.
The fitting time is between 1.5-3 seconds.
The laminate pressure of the fitting is between million pa of 0.3-0.5.
[Detailed description of the invention]
Fig. 1 is the display picture generation Newton's ring phenomenon schematic diagram for commonly using display pannel；
Fig. 2 is diaphragm and liquid crystal cells above the backlight module for commonly using display pannel
Absorption schematic diagram in part occurs for lower layer's polaroid；And
Fig. 3 is the backlight modular structure sectional view of inventive display panel.
[specific embodiment]
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate the present invention with reference to additional diagram Example.The direction term that the present invention is previously mentioned, such as [on], [under], [preceding], [rear], [left side], [right side], [interior], [outer], [side] Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to The limitation present invention.
Below with reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete Site preparation description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those skilled in the art's every other implementation obtained without creative efforts Example, shall fall in the protection scope of this application.
Referring to FIG. 3, this preferred embodiment is provided respectively from the glue frame frame veneer of the glue frame 110 of backlight module 20, backlight The protective film 103 and diaphragm 102 of the diaphragm 102 of 20 top of module are bonded parameter etc. with glue frame 110, implement to strengthen To solve display picture Newton's ring phenomenon occurs for the method for producing panel of the structural stability measure of backlight module 20.
Referring to FIG. 3, the frame veneer of the glue frame 110 of backlight module 20 is cemented with glue-line 104 with the diaphragm 102 above it.
A kind of there is the panel of Newton's ring phenomenon for solving picture on display pannel in what this preferred embodiment was proposed Manufacturing method includes: to be roughened on the frame veneer of the glue frame 110 of backlight module 20, for promoting the glue frame Pull-out capacity of the 110 frame veneer to the diaphragm 102 of 104 top of glue-line 104 and glue-line above it；Reduce by 20 top of backlight module The off-type force of protective film 103 above diaphragm 102 (such as a brightness enhancement film), when for reducing removing the protective film 103, to it Pulling force caused by the glue-line 104 of 102 lower section of diaphragm 102 and diaphragm of lower section；And the glue in diaphragm 102 and backlight module 20 In the fitting of frame 110, extend the fitting time, is binded for increasing the diaphragm 102 and the frame veneer of the glue frame 110 of backlight module 20 Power.
The roughening treatment uses electrical discharge machining means.
